* 1 Fan motor will rotate for a while after cooking.
* 2 Antenna motor will rotate only when high voltage transform-
er is energized.
* 3 Grill heating element will be energized for 30 seconds be-
fore end of cooking.
* 4 Engine heating element will be turned on and off by temper-
ature of thermistor (engine).
* 5 Intake damper motor will rotate until a damper is closed
when cooking is started. And intake damper motor will ro-
tate until a damper is opened after the end of cooking.
* 6 Tube pump motor will turned on and off by temperature of
thermistor (engine).

[3] OFF CONDITION

1. When the oven is plugged in with the door closed, the line voltage is supplied to the noise filter. And the display shows nothing.
2. When the door is opened with plugged in, the contacts (COM-NC) of the monitored interlock switch is closed. And the line voltage is supplied to
the T/C transformer and the control unit. Then the contacts of the relay RY-9 are closed and the contacts of the relay RY-1 are closed. And the
oven lamp is turned on.The display shows "0.".
3. When the door is closed, the contacts (COM-NC) of the monitored interlock switch are opened. Because the contacts of the relay RY-9 have been
closed, the line voltage is kept supplying to the T/C transformer and the control unit. But the contacts of the relay RY-1 are opened and the oven
lamp is turned off.
Energy save mode
If the door is closed and any key is not pressed for more than 3 minutes except for the following 10 conditions, the contacts of the relay RY-9 will be
